Abstract
Plants have developed a variety of mechanisms to compensate for the cost of biotic and/or abiotic stresses. Upon parasite infection, host may respond differently, wich may be categorized into different strategies. While some are well charecterized, tolerance has received less atention. Tolerance can be defined as a compensation of the negative effects of parasitism in the host fitness, often associated to modifications of life history traits. Life-history theory makes predictions for the adjustment of resource investment by organisms, based on the notion that trade-offs exist between resources allocated to diferent fitness components: growth, reproduction and survival. Models for evolution of resource allocation predict that parasitized organisms will allocate more resources to reproduction, substracting them from those dedicated to growth and survival..Our group tested these predictions in the plant-parasite system of Arabidopsis thaliana and the generalist virus Cucumber mosaic virus (CMV).
